One great challenge that faces
broadband networks is the ability to provide guaranteed performance to diverse
traffic types based on their quality of service (QoS) requirements, while at
the same time efficiently utilizing the network capacity. Many issues are
involved in such performance-driven problems, including the type of guarantees
required, traffic characteristics, congestion control mechanisms implemented at
various nodes along the patch, bandwidth allocation algorithms, and buffer
management schemes. Altogether, these factors determine the performance of the
network.

Therefore, the main goal of my research
is to develop efficient techniques and accurate models that can be used to
provide QoS guarantees for communicating sessions in ATM-based networks.
Relevant issues will be studied during the course of this research by using
actual performance data from our ATM testbed. Examples of general research
topics within the domain of QoS which are currently being studied include:
